Things about reindeer and other animals even though we did things about reindeer already

The reindeer also known as the caribou is an animal that lives in North America and also in Russia is another species of the common deer. Reindeer are not endangered however they are threatened to become endangered but they are also one of the least of our threats(I know it does not make any sense).
Now we talk about a different animal even though that was really short, the penguin is a popular bird species because it cannot fly. They have a steady population and are not close to being endangered or extinct. They are known for how they look and how they act, and also because they look cute from a distance. Now another animal, the pigeon comes from a bird family called the Columbidae, they have a worldwide presence but they vary more in Indonesia and Australasia. Their population is huge, there is a lot of them around the world and they all look very similar. Now the final random animal is a Giraffe, the giraffe is known for its long neck and it is native to parts of Africa. It is also known as one of the largest terrestrial animals at this time specifically, maybe way not back then since dinosaurs were a thing.
